UNITED STATES PATENT OFFICE.

FREDERICK W. DUNTON, OF HOLLIS, NEW YORK, ASSIGNOR TO EMILY M. DUNTON, OF SAME PLACE.

SING LE-RAIL-RAI LWAY CAR.

SPECIFICATION forming part of Letters Patent No. 592,866, dated November 2, 1897.

' Application filed July 29, 1897- Serial No. 646,288. (No model.)

To all whom it may concern:

Be it known that I, FREDERICK W.DUNTON, a citizen of the United States, and a resident of Hollis, in the county of Queens and State of New York, have invented certain new and useful Improvements in Single-Rail-Railway Cars, of which the following is a specification.

This invention I relates to a railway-car ofthe class which travels on 'a single bottom rail and is sustained by means of a single overhead guide-rail.

The invention is designed more particularly to impart motion to such car in a simple, direct, and efficient manner by a motor which is supported by the car-truck and is coupled to the traction-wheel by direct gear.

In the accompanying drawings, Figure 1 is a side elevation, partly in section, of a railwaycar embodying my invention; Fig. 2, an enlarged sectional side view of the truck, and Fig. 3 a sectional plan thereof.

The letterArepresents the body of the car, which is supported at each end by a truck consisting, essentially, of a square frame a, the two longitudinal sides of which are provided with boxes a to receive the axle b of the traction-Wheel c. The car-body is so mounted upon the truck that the latter has a free rotary motion, and to this effect the carbody is provided with a pair of spring-supported beams d, having segmental cornerplates d, that are engaged on their lower sides by antifriction-rolls a journaled in the corners of frame 0,. A second set of rolls (1, hung to the beams d on vertical axes and engaging curved corner-plates a? of frame a, constitute in effect a fifth-wheel that permits free rotary motion of the truck.

In order to guide the car along the upper rail B of the track, the frame a is provided with an upwardly-extending yoke c, which projects through and above the car-body and the side rails.

carries at its top the guide-rolls e, which engage the sides of the upper rail. All this is more fully described in Patent No.- 562,218, granted to me June 16, 1896.

To the end rails of frame a there is attached, at a short distance from one of its side rails, a longitudinal beam f, which constitutes the support for one end of an electric motor 9, the other endof which is supported by one of The axle g of thismotor is placed parallel to the Wheel-axle b and within the periphery of the'traction-wheel c. This wheel is provided with an internal circumferential gear 0', engaged by a pinion 9 mounted upon the motor-axle g. Thus motion is transmitted from the motor-axle to the tractionwheel by direct gear, and as all the parts are supported upon the truck-frame their relative position will remain undisturbed, without re gard to the relative position between truck and car-body.

It will be seen that in my improved railwaycar the traction-Wheel is centered within the fifth-wheel and is directly intergeared with the motor. In this way freedom of motion for the truck is insured and a compact connection between traction-wheel and motor is effected.

What I claim is In a single-rail-railway car the combination ,of a traction-wheel having an internal gear with an electric motor having a pinion that engages such wheel, a supporting-frame, and with a fifth-wheel within which the tractionwheel is centered, substantially as specified.
